HEART
The system responsible for making new blood cells is the hematopoietic system, primarily located in the bone marrow. This process, known as hematopoiesis, involves the differentiation of stem cells into various types of blood cells, including red blood cells, white blood cells, and platelets. Additionally, organs like the spleen and liver play supportive roles in blood cell production and maturation.
In adults they are mostly produced in the bone marrow. There are situations where they can be produced elsewhere.
Three maion cells are: -Red Blood Cells (carries CO2 away) -White Blood Cells (fights infections by making antibodies) -Platelets (Form scabs and blood clots) They are all suspended in the plasma which carries the Oxygen.
The largest structure in the lymphoid system is the spleen. It is responsible for filtering blood, storing blood cells, and producing antibodies to help fight infection.
There are various cells and organs that plays a vital role in the production of antibodies. Primarily the white blood cells also called as lymphocytes converts to immunoblasts and then convert to plasma cells, from which the antibodies are thus produced. T-cells and B-cells are antigen specific and produce the antibodies based on the structure and pathogenticity of an antigen. The immune response varies from one antigen to the other.
the red cell is responsible for carrying oxygen to the cells of the body and taking up carbon dioxide and returning it to the lungs so it can be released from the body. red blood cells a circular and biconcave in shape ,they are are elastic and so can pass through any small capillaries making the blood flow easy They turn red from oxygen reacting with the hemoglobin in them. A sickler's red blood cells are semi-circular.
The blood cells responsible are red blood cells. White blood cells fight disease.
White blood cells ( WBC), Red blood cells( RBC), and finally platelets. White blood cells are the cells that are responsible for the immunity of the cells, while red blood cells contain the oxygen containing pigment heamoglobin, and platelets are fragments of cells that are responsible for clotting.
The structure involved in the breakdown of red blood cells are called macrophages. Macrophages are white blood cells that are in connective tissues. They are formed to accumulate damaged or dead cells.
Bone and blood cells are considered to be specialized types of cells that play crucial roles in the body's overall functioning. Bone cells are responsible for maintaining the integrity and structure of the skeletal system, while blood cells are essential for transporting oxygen, nutrients, and waste products throughout the body.
The basic structure of the marrow becomes abnormal, and those cells responsible for generating blood cells (hematopoietic cells) are greatly decreased in number or absent.
The structure responsible for the restriction of movement of large complex substances into the bloodstream is the endothelial cells that line blood vessels. These cells form a barrier known as the blood-brain barrier, which regulates the entry of substances from the bloodstream into the brain and spinal cord to protect the central nervous system.
