Match each blood part with the correct description.

1. prevents body from losing blood after injury
plasma
2. fights off disease in the body
red blood cells
3. carries oxygen around the body
white blood cells
4. is made of 90% water
platelets

Answers

1- platelets
2- white blood cells
3- red blood cells
4- plasma

The matching of each blood part with the correct description is as follows:

Prevents body from losing blood after injury: PlateletsFights off disease in the body: White blood cells. Carries oxygen around the body: Red blood cells. It is made of 90% water: Plasma.

What are the functions of the blood?

The functions of the blood are as follows:

It transports oxygen and other required nutrients to the lungs and tissues.It significantly constructs blood clots in order to prevent excess blood loss during injury.Blood while flowing carries cells and proteins known as antibodies which fight against infections.It regulates body temperature.

The flowing blood is a very complex mechanism. This is because it prevents the mixing of carbon dioxide rich-blood which we get from the cells and tissues to the oxygen-rich blood which we get from the heart and transport to the lungs.

Each component of the blood plays an active role in order to function properly and increases the chances of survival by the elimination of infections.

Therefore, the matching of each blood part with the correct description is well-described above.

4. What do you think could happen if the human body doesn’t take in one or all of these molecules? Why do you think this?

Answers

Answer:

1. Glucose molecules come from the food we eat. we digest the food, then it mixes with acid/enzymes in the stomach. then the food breaks down and becomes glucose (blood sugar).

2. the best place to get amino acids is through protein-rich foods. when you eat protein, it gets broken down into amino acids, which are used for building muscle and "regulating immune function"

3. enters through the alveoli. it exchanges with older air in the lungs.

4. A. glucose- cause low blood sugar, causing problems in your nervous system

B- amino acids-decreased immunity, fertility issues, slowed growth (in children), digestion problems, and depression.
