The liver functions to regulate nutrient levels in the blood, store carbohydrates, iron, vitamins A and D, and synthesize plasma proteins and cholesterol. It also plays a key role in detoxification by breaking down old red blood cells and filtering toxins from the blood via the hepatic portal vein and sinusoids before blood exits through the hepatic vein. Excessive alcohol consumption can damage the liver by disrupting these important functions.
Body fluids, composition and functions of blood, hemopoeisis, formation of
hemoglobin, anemia, mechanisms of coagulation, blood grouping, Rh factors,
transfusion, its significance and disorders of blood, Reticulo endothelial system.

This presentation gives you the knowledge about the body fluids, blood components, the process of blood clotting, blood grouping. It is helpful to determine the knowledge of human blood.

BLOOD composition&functions of blood,plasma proteins
Blood is a connective tissue in fluid form.
It is considered as the ‘fluid of life’ because it carries oxygen from lungs to all parts of the body and carbon dioxide from all parts of the body to the lungs.
It is known as ‘fluid of growth’ because it carries nutritive substances from the digestive system and hormones from endocrine gland to all the tissues.
The blood is also called the ‘fluid of health’ because it protects the body against the diseases and gets rid of the waste products and unwanted substances by transporting them to the excretory organs like kidneys
function
1. Nutrient Function:
Supplies nutrients like glucose, amino acids, lipids.
2. Respiratory:
carries oxygen to the tissues and transport CO² to lungs for expiration.
3. Excretory:
removes waste products from tissues and carried to the excretory organs like kidneys, skin, liver etc.
4. Regulation of body temperature
5. Defensive function:
WBCs are responsible for this function (Neutophils and monocytes) engulf the bacteria by phagocytosis.
Lymphocytes are involved in immunity.
Eosinophils are responsible for detoxification, disintegration( to break or separate into constituent elements or parts) and removal of foreign proteins.
6. Storage function
Blood cells:
1) Red blood cells or Erythroctes.
2) White blood cells or leukocytes.
3) Platelets or Thrombocytes.
Plasma is the intercellular matrix of the blood
Composition of plasma
Plasma Proteins 7-9%
Albumin
Globulin
Fibrinogen
Dissolved solutes 3%
Water 90%
albumin
Smallest in molecular weight
Synthesized by liver
Provide osmotic pressure. This is needed to maintain volume and pressure of blood
GLOBULIN
Transport and storage proteins
TYPES :
Alpha & beta : transport lipids and fat soluble vitamins (liver)
Gamma globulins : antibodies produced by lymphocytes
(IgD) belong to the group of gamma globulins and serve as defense proteins (antibodies).
IgG is the most abundant immunoglobulin, can cross the placental barrier (maternofetal transmission).
fibrinogen
Imp. clotting factor
Largest molecular weight
Helps in coagulation of blood
All the plasma proteins are synthesized in liver except ?? Gamma globulins (which are derived from B cells)
What is difference between plasma and serum ??
Plasma – fibrinogen = serum

2. H.4.1 Outline the circulation of blood through liver tissue, including
the hepatic artery, hepatic portal vein, sinusoids and hepatic vein.
The difference in structure between sinusoids and capillaries
should also be mentioned. Reference to lobules or acini is not
required.
H.4.2 Explain the role of the liver in regulating levels of nutrients in
the blood.
H.4.3 Outline the role of the liver in the storage of nutrients,
including carbohydrate, iron, vitamin A and vitamin D.
H.4.4 State that the liver synthesizes plasma proteins and
cholesterol.
3. H.4.5 State that the liver has a role in detoxification.
H.4.6 Describe the process of erythrocyte and hemoglobin
breakdown in the liver, including phagocytosis, digestion of globin
and bile pigment
formation.
H.4.7 Explain the liver damage caused by excessive alcohol
