MindMap Gallery Transport of substances in the human body
In the second volume of seventh grade, the knowledge about the transportation of substances in the human body is sorted out, and the knowledge about blood, blood vessels, heart, blood transfusion and blood types is shared. I hope this brain map will be helpful to you.

Transport of substances in the human body
blood 🩸
plasma
Composition: 90% water, 7% plasma protein, glucose, amino acids, inorganic salts, etc.
Function: Carry blood cells, transport nutrients needed for human life activities and waste products produced in the body
blood cells
red blood cells
Composition: Contains hemoglobin, large amount, mature red blood cells without nuclei
Function: Transport oxygen/deficiency: iron deficiency anemia
leukocyte
Composition: Large in size, small in number, with nuclei
Function: Phagocytosis of bacteria and viruses / If the number is higher than normal: inflammation
platelets
Composition: The smallest blood cell, irregular shape, no nucleus
Function: Stop bleeding and accelerate coagulation/If the number is higher than normal: Thrombus
blood vessels 🌡
artery
Function: Send blood from the heart to all parts of the body
Features: Thick wall, high elasticity, fast blood flow in the tube
vein
Function: Return blood from all parts of the body to the heart
Features: thin tube wall, low elasticity, slow blood flow
capillaries
Blood vessels connecting the smallest artery and smallest vein
Features
The largest number and the widest distribution
The inner diameter is small, allowing only red blood cells to pass through in a single file
The tube wall is thin and consists of only a layer of flat epithelial cells
Blood flow is the slowest
heart 🫀
Location
In the center of the chest, lower left, between the lungs
structure
Left atrium - pulmonary veins
Left ventricle (thickest wall of the heart) – aorta
Right atrium - superior and inferior vena cava
Right ventricle - pulmonary artery
valve
Classification
arterial valve
venous valve
intercourse valve
Function: Prevent blood from flowing backward
blood circulation
Systemic circulation: left ventricle → aorta → arteries at all levels → systemic capillaries → veins at all levels → superior and inferior vena cava → right atrium
Pulmonary circulation: right ventricle → pulmonary artery → pulmonary capillaries → pulmonary veins → left atrium
Blood transfusion and blood type
blood type
Type A, Type B, Type AB, Type O
Universal blood recipient—type AB
Universal transfusion patient - Type O
blood transfusion
Massive blood transfusion - same type of blood transfusion
my country implements voluntary blood donation for healthy citizens aged 18 to 55 years old
