Which of the following membranes forms the outer lining of the lungs
Correct Answer
D. Visceral pleura
Explanation
The visceral pleura forms the outer lining of the lungs. The visceral pleura is a thin, serous membrane that covers the surface of the lungs and is closely attached to the lung tissue. It helps to protect and lubricate the lungs, allowing them to expand and contract smoothly during breathing. The parietal pleura, on the other hand, lines the inside of the chest cavity, while the visceral peritoneum is the membrane that covers the organs in the abdominal cavity. The meninges are membranes that surround and protect the brain and spinal cord.
11.
Which of the following is most related to a carcinoma and sarcoma?
Correct Answer
B. Cancer
Explanation
Carcinoma and sarcoma are both types of cancer. Carcinoma refers to cancer that starts in the epithelial cells, which are the cells that line the organs and tissues of the body. Sarcoma, on the other hand, refers to cancer that starts in the connective tissues, such as bones, muscles, and blood vessels. Therefore, the term "cancer" is the most related to both carcinoma and sarcoma, as it encompasses all types of malignant tumors that can occur in different parts of the body.
12.
Which type of membrane lines the body cavities that open to the exterior part of the body?
Correct Answer
C. Mucous membrane
Explanation

It is found in various areas such as the respiratory tract, digestive system, and reproductive system. The mucous membrane plays an important role in preventing pathogens from entering the body and helps to maintain the health and function of these body cavities.
13.
Which of the following is most descriptive of a bed sore?
Correct Answer
A. Decubitis ulcer
Explanation
A bed sore, also known as a decubitis ulcer, is a localized injury to the skin and underlying tissue caused by prolonged pressure on the skin. It typically occurs in individuals who are bedridden or have limited mobility, as constant pressure on certain areas of the body reduces blood flow and damages the skin. The term "decubitis ulcer" accurately describes this condition, whereas the other options (sarcoma, malignant neoplasm, metastatic) are unrelated to bed sores.
14.
Which of the following is most related to a mucous membrane?
Correct Answer
B. Lines all the body cavities that open to the exterior part of the body
Explanation
A mucous membrane is a thin, moist layer of tissue that lines various body cavities and structures that open to the outside of the body, such as the respiratory, digestive, and reproductive systems. It helps to protect these cavities from infection, traps foreign particles, and produces mucus to keep the tissues moist. The option "lines all the body cavities that open to the exterior part of the body" accurately describes the function and location of a mucous membrane. The other options, dermis, skin, and epidermis, are not directly related to mucous membranes.
15.
Which type of membrane lines the ventral body cavities that are not open to the exterior body?
Correct Answer
A. Serous membrane
Explanation
The serous membrane lines the ventral body cavities that are not open to the exterior body. This type of membrane secretes a lubricating fluid that helps reduce friction between organs and allows them to move smoothly. It consists of two layers: the parietal layer, which lines the cavity walls, and the visceral layer, which covers the organs. The serous membrane is found in cavities such as the pleural cavity (around the lungs), pericardial cavity (around the heart), and peritoneal cavity (around the abdominal organs).
16.
Which of the four major tissue types are able to regenerate and repair quickly when injured?
Correct Answer
C. Epithelial
Explanation
Epithelial tissue is able to regenerate and repair quickly when injured. This is because epithelial cells are tightly packed together and have a high rate of cell division. When injured, the surrounding healthy epithelial cells can quickly divide and migrate to cover the damaged area, forming a new layer of tissue. This rapid regeneration helps to protect underlying tissues and maintain the barrier function of epithelial surfaces. In contrast, nervous, muscle, and connective tissues have limited regenerative capacity and may require more time and specialized processes to repair injuries.
17.
Which of the following is true of an exocrine gland?
Correct Answer
C. Secretes in products to the outside or onto the surface
Explanation
An exocrine gland is a type of gland that secretes its products onto the surface of an organ or directly into a duct that leads to the external environment. This means that it secretes its products to the outside or onto the surface. Exocrine glands are not made of connective tissue, as they are typically composed of epithelial tissue. They also do not secrete hormones, as that is the function of endocrine glands. Finally, exocrine glands do not only secrete sweat, as there are various types of exocrine glands in the body that secrete different substances such as saliva, digestive enzymes, or oil.
18.
Which of the following is most related to blood?
Correct Answer
B. Plasma
Explanation
Plasma is the correct answer because it is the liquid component of blood, making up about 55% of its total volume. It is responsible for transporting various substances such as nutrients, hormones, waste products, and antibodies throughout the body. Plasma also plays a crucial role in maintaining blood pressure and regulating body temperature.

This type of tissue allows for rapid diffusion of oxygen from the aveoli in the lungs to the blood
Correct Answer
C. Simple squamous
Explanation
Simple squamous tissue is a single layer of flat cells that allows for rapid diffusion of oxygen from the alveoli in the lungs to the blood. This tissue is thin and allows for efficient exchange of gases due to its large surface area. It is found in the walls of the alveoli, which are the tiny air sacs in the lungs responsible for oxygen exchange with the bloodstream. Simple squamous tissue is well-suited for this function because it allows for easy passage of oxygen molecules through its thin and permeable structure.
23.
Ligaments is best described as
Correct Answer
C. Tough bands of connective tissue
Explanation
Ligaments are tough bands of connective tissue that connect bones to other bones, providing stability and support to joints. They are composed of dense fibrous tissue, mainly collagen, which gives them their strength and flexibility. Ligaments play a crucial role in maintaining the integrity and function of joints, allowing for proper movement and preventing excessive or abnormal joint motion. Unlike the other options, ligaments are not related to malignancy or epithelial tissues.
24.
Endocrine and exocrine glands are
Correct Answer
B. Epithelial tissue
Explanation
Endocrine and exocrine glands are classified as epithelial tissue because they are derived from the epithelial layer during embryonic development. Epithelial tissue is responsible for the secretion of hormones (endocrine glands) and substances such as enzymes and sweat (exocrine glands). These glands are composed of specialized epithelial cells that are organized in a way to facilitate secretion and transportation of substances. Connective tissue, adipose tissue, and glial tissue do not have the same function or structure as epithelial tissue, making them incorrect choices.
25.
