What is blood? Describe its composition.?

Question

Answer

Blood is a red coloured liquid which circulates in our body.it consist  RBC, WBC, plasma and platelets.

Answer

Blood is a connective tissue which compromises of blood corpuscles it also perform many functions like transportation of food to each cell for it's energy .it also maintain body temperature.flow of nutrition and hormone throughout our body occurs due to fluid''blood'

Answer

Blood makes up about 8% of the human body weight. It containserythrocytes, leucocytes,thrombocytes (platelets) and plasma. The volume percentage of all blood cells in the whole blood is about 45% of adults (hematocrit). The rest consists of liquid plasma (e.g. water,plasma proteins, electrolytes etc.).

Answer

Introduction

Blood is a vital fluid that circulates throughout the human body, delivering essential substances such as oxygen, nutrients, hormones, and immune cells to various organs and tissues. It is a complex mixture of cells, proteins, and other molecules suspended in a fluid called plasma.

Composition of Blood
Blood consists of several components, each playing a crucial role in maintaining normal bodily functions. These components include:

1. Red Blood Cells (RBCs): RBCs, also known as erythrocytes, are the most abundant cells in the blood. They are responsible for transporting oxygen from the lungs to the body's tissues and carry carbon dioxide back to the lungs for elimination.

2. White Blood Cells (WBCs): WBCs, also called leukocytes, play a vital role in the immune system. They help defend the body against infections, pathogens, and foreign substances. There are different types of WBCs, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils, each with unique functions.

3. Platelets: Platelets, or thrombocytes, are small, cell-like structures involved in blood clotting. When a blood vessel is damaged, platelets aggregate at the site to form a clot, preventing excessive bleeding.

4. Plasma: Plasma is a yellowish fluid that makes up about 55% of blood volume. It mainly consists of water, electrolytes, proteins, hormones, waste products, and other substances. Plasma transports nutrients, hormones, and waste products throughout the body and helps regulate body temperature.

Key Points:
- Blood is a vital fluid that circulates throughout the body.
- It consists of red blood cells, white blood cells, platelets, and plasma.
- Red blood cells transport oxygen, while white blood cells defend against infections.
- Platelets are involved in blood clotting.
- Plasma is the fluid component of blood and transports nutrients and waste products.

In conclusion, blood is a complex mixture of cells and molecules that carries out essential functions in the human body. Understanding its composition is crucial for diagnosing and treating various diseases and disorders.

Answer

Blood is a fluid connective tissue which connects all the organs inside the body and carry oxygen and absorbed food to all the body parts . Blood is composed of blood plasma , red blood cells, white blood cells and blood platelets
