Biology 8 Lesson 40: Hygiene of the urinary system
1. Summary of theory
1.1. Some factors are mainly harmful to the urinary system
When the glomeruli become inflamed and degraded, it can lead to serious health consequences such as:
+ The dialysis process is delayed -> Residues and toxic substances accumulate in the blood -» The earliest manifestation is edema, followed by total kidney failure leading to coma and death.
– When the renal tubular cells work less efficiently —> The process of reabsorption of necessary substances and excretion of toxic waste products is reduced -> The internal environment is changed -> Metabolism is disturbed disorder —> Adverse effects on health.
+ When the renal tubular cells are damaged, they can block the tubules or the urine in the tubules can be mixed directly into the blood -> Poisoning the body with symptoms similar to cases of kidney failure.
– When the urinary tract is blocked by stones, causing urinary retention or inability to urinate
+ The patient is in severe pain and may have a fever
If not treated promptly, it can also be life-threatening.
1.2. It is necessary to develop scientific living habits to protect the urinary excretory system
2. Illustrated exercise
Lesson 1: Why is the urine often smelled of antibiotics when treating the disease with antibiotics?
A. Signs of bacteria entering the urinary tract
B. The amount of other drugs given to the patient is in excess
C. Antibiotics reach the kidney units to kill bacteria in the blood
D. Antibiotics are taken out of the body by excretion
- Choose the answer: EASY
- Explanation: Antibiotics are usually formulated to stay in the body for a certain time, after which they either break down or are excreted in the urine.
Lesson 2: Why do I not feel the urge to urinate for a long time?
A. The body excretes water by other ways
B. Urine is formally transported back for reabsorption
C. The brain doesn’t give the “need to pee” signal anymore
D. All of the above answers are incorrect
- Choose the answer: NO
- Explanation: If the bladder is too distended for a long time, some urine will be transported back to the renal tubules and reabsorbed.
Lesson 3: How can the human urinary system be harmed?
– You can answer according to the following suggestions:
- How can the glomerulus be damaged?
- How can the renal tubules be damaged?
- How can the urinary tract be damaged?
3.1. Essay exercises
Question 1: In the scientific life habits to protect the urinary system, what habits do you have and do not have?
Verse 2: Try to come up with a plan to form a scientific life habit if you haven’t already.
Question 3: How to have a healthy urinary system? Explain the scientific basis of those measures?
3.2. Multiple choice exercises
Question 1: What stages occur in the formal production of urine?
A. Generating primary urine, transporting urine input to the bladder, reabsorption.
B. Generate primary urine, reabsorb in glomerular follicles, transport to the bladder.
C. Create first urine, reabsorbed in the renal tubule, excreted.
D. Make urine first, reabsorb, transport back to the glomerulus.
Verse 2: Which habits are good for kidney health?
A. Eat a lot of salty foods.
B. Eat lots of water.
C. Holding urine for a long time.
D. Exercise regularly.
Question 3: Which agent indirectly damages the kidney?
A. Salty food
B. Eat foods high in cholesterol (1 stone-forming ingredient)
C. Invasion of bacteria causing inflammation of other organs
D. Long time holding urine
Verse 4: What is not the cause of frequent urination at night?
A. Strong exercise
C. Kidney stones
D. Kidney failure
Question 5: Which agent does not interfere with urine excretion?
A. Kidney stones
C. Bacteria that cause inflammation
D. Blood pressure
– After studying this lesson, you will need
• Describe the harmful agents to the urinary system and its consequences.
• Present scientific lifestyle habits to protect the excretory system and explain their scientific basis.
