SiSTEMa Urinário

During the process of urine formation, the kidneys filter waste products, excess water, and electrolytes from the blood. The correct answer states that reabsorption of water and minerals occurs during this process. This means that the kidneys reabsorb these substances back into the bloodstream, helping to maintain the body's balance of fluids and electrolytes. Elimination of erythrocytes (red blood cells), proteins, or carbohydrates is not a normal part of urine formation.

The correct answer is uretra. The question is asking for the canal through which urine is eliminated from the bladder to the outside. The urethra is the tube that connects the bladder to the external urethral orifice and allows urine to pass out of the body. The kidneys filter waste products from the blood to produce urine, which then travels through the ureters to the bladder. From the bladder, urine is expelled through the urethra during urination.

This statement does not refer to the urinary system because the urinary system is responsible for maintaining the concentration of fluids, filtering harmful substances from the blood, and regulating water concentration. It does not cause imbalance in the human body.

The correct answer is "transportar as excreção de todas as células até aos rins." This is because the circulatory system is responsible for transporting waste products, including excretions, from all cells in the body to the kidneys, where they can be filtered and eliminated from the body.

The question is asking for the organ in the urinary system that has elastic walls. The correct answer is the bladder. The bladder is a muscular organ that stores urine and expands as it fills up. Its walls are stretchable and elastic, allowing it to accommodate varying amounts of urine. The kidneys, ureters, and urethra are also part of the urinary system, but they do not have the same elastic properties as the bladder.

A alimentação desequilibrada não representa um cuidado a ter com o sistema urinário. A ingestão de água é importante para manter o sistema urinário saudável, pois ajuda a diluir a urina e a eliminar toxinas. Os hábitos de higiene, como limpar adequadamente as áreas genitais, também são essenciais para prevenir infecções urinárias. Além disso, uma alimentação com baixo teor de sal é benéfica para o sistema urinário, pois o excesso de sal pode levar à retenção de líquidos e aumentar a pressão arterial.

Metano não é um produto da atividade celular porque é um gás encontrado principalmente em fontes naturais, como pântanos e reservatórios subterrâneos de petróleo e gás. Embora certas bactérias possam produzir metano como subproduto de seu metabolismo, ele não é considerado um produto típico da atividade celular. Por outro lado, dióxido de carbono, ácido úrico e ureia são produtos comuns da atividade celular em organismos vivos.

The correct answer is "a uretra e os ureteres." This is because the uretra and the ureters are both part of the urinary system. The uretra is a tube that carries urine from the bladder to the outside of the body, while the ureters are tubes that carry urine from the kidneys to the bladder. The kidneys are also part of the urinary system, but they are not mentioned in the answer options. The bexiga (bladder) is mentioned, but it is not a constituent of the urinary tract.
