Biology 8 Lesson 35: Review term 1
1. Summary of theory
1.1. Systematization of knowledge
a. Overview of the human body
1.2. Movement of the body
1.6. Metabolism and metabolism
- The respiratory system takes O2 from the environment to supply to the organ systems and releases CO2 into the environment through the circulatory system.
- The digestive system takes food from the external environment and converts it into nutrients to supply all systems through the circulatory system.
- The excretory system helps to remove waste products from the metabolism of all organ systems to the external environment through the circulatory system.
2. Illustrated exercise
Within the scope of your knowledge, prove that cells are the structural and functional units of life.
a. Cells are structural units
All organs of the body are made up of cells.
– For example, bone cells, muscle cells, vascular epithelial cells, red blood cells, white blood cells, epidermal cells in the gastric mucosa, gland cells, etc.
b. Cells are functional units
– Cells participate in the functional activities of organs.
+ The action of myofibrils in the cell helps muscles contract, relax,
Cardiac muscle cells contract and relax, helping the heart to contract, creating force to push blood into the vascular system.
Glandular cells secrete secretions into the digestive tract to chemically transform food.
