The main cells of the respiratory system include epithelial cells, specifically ciliated columnar and goblet cells, which line the airways and help to trap and expel debris and pathogens. Alveolar type I and type II cells are crucial in the alveoli; type I cells facilitate gas exchange, while type II cells produce surfactant to reduce surface tension. Additionally, immune cells like macrophages help protect against infections in the lung tissue. These cells work together to ensure efficient breathing and lung health.
No
The white blood cells are the structured main base in the immune system.
Hemoglobin is the main constituent of red blood cells, and as such, it belongs to the circulatory system.
The main system that serves the needs of individual cells in multicellular organisms is the circulatory system. This is used to take waste away from individual cells and bring in new fuel such as proteins, glucose, and oxygen.
The main organ of the circulatory system is the heart. It pumps blood throughout the body, delivering oxygen and nutrients to cells and removing waste products.
phagocyte is the main cell of immune system
Neurons and glia cells
The white blood cells are the structured main base for the immune system.
No
macrophages, killer T cells, helper T cells, and B cells
The white blood cells are the structured main base in the immune system.
Hemoglobin is the main constituent of red blood cells, and as such, it belongs to the circulatory system.
white blood cells, they raid off bacteria
To transport nutrients and oxygen to the cells of the body.
For non-insects, its the transportation of oxygen and nutrients to the cells and wastes away from the cells.
Erythrocytes are red blood cells that have the main function of delivering oxygen to cells in the body. Leukocytes are white blood cells that are associated with the immune system.
The main system that serves the needs of individual cells in multicellular organisms is the circulatory system. This is used to take waste away from individual cells and bring in new fuel such as proteins, glucose, and oxygen.
