Description

"Flowing Tissue-Blood" Transport of Materials in the Human Body PPT Courseware 5

learning target:

1. Components of blood;

2. Understand the functions of plasma and blood cells.

Independent learning and independent answers:

1. What tissue of the human body is blood, and what functions does it have?

2. What does blood consist of? What types of blood cells are there?

3. What are the components of plasma and what functions does it have?

4. What are the main items of routine blood tests?

Contact with reality:

1. After exercise, you sweat a lot. What components are lost in the blood? How to replenish these components lost in the blood?

When sweating a lot, the blood mainly loses water and some inorganic salts. Drinking water and appropriate amounts of inorganic salts are usually used to replenish the components lost in the blood. In severe diarrhea, the human body mainly loses nutrients such as water, some inorganic salts, and glucose. Methods such as drinking water, supplementing appropriate amounts of inorganic salts, and intravenous drip (or oral) glucose are usually used.

2. When rescuing a patient with extensive burns, should blood or plasma be transfused?

Plasma and blood will coagulate outside the body, so when donating blood, donate plasma

experiment

Observing a permanent smear of human blood using a microscope

Experiment purpose: Understand red blood cells and white blood cells

Materials and tools: permanent smear of human blood, white blood cells.

Method steps:
