What makes up sweat?
- A.
Water
- B.
Water and minerals the body does not need
- C.
water and minerals the body needs
Correct Answer
B. Water and minerals the body does not needExplanation
Sweat is primarily composed of water and minerals that the body does not need. When the body gets overheated, it produces sweat as a way to cool down. Sweat helps regulate body temperature by evaporating from the skin's surface. In addition to water, sweat also contains small amounts of minerals like sodium, potassium, and chloride. These minerals are excreted through sweat, helping to maintain the body's electrolyte balance. However, the body does not require excessive amounts of these minerals, which is why they are considered as substances that the body does not need.Rate this question:

- D.
Glomerulus
Correct Answer
D. GlomerulusExplanation
After blood enters the kidney, it travels to the glomerulus. The glomerulus is a network of tiny blood vessels called capillaries that are responsible for filtering waste products and excess fluid from the blood. The blood is forced through the capillaries under high pressure, allowing small molecules such as water, salts, and waste products to pass through into the surrounding structures, while larger molecules like proteins and blood cells are retained in the blood. This initial filtration process in the glomerulus is the first step in the formation of urine in the kidneys.Rate this question:
