Explores the different types of body fluids, their composition, and how they move through the circulatory and lymphatic systems.
The normal blood pressure is about 120/80 mmHg, not 90/60 mmHg (which indicates low blood pressure).

Hemoglobin does bind to carbon dioxide, transporting it from tissues to the lungs for exhalation.

Arteries have thick muscular walls to withstand high blood pressure exerted by the pumping action of the heart.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Circulatory System - Comparative and Evolutionary Aspects
The pulmonary arteries carry deoxygenated blood from the heart to the lungs.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Circulatory System - Comparative and Evolutionary Aspects
Coronary arteries supply oxygenated blood to the cardiac muscle to ensure proper heart function.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Circulatory System - Comparative and Evolutionary Aspects
Pulmonary veins carry oxygenated blood from the lungs to the heart, so not all veins carry deoxygenated blood.

Mature RBCs lack a nucleus, which increases their space for hemoglobin and oxygen transport.

Erythroblastosis fetalis occurs when an Rh-negative mother carries an Rh-positive fetus.

Systemic circulation carries oxygenated blood from the heart to the body's tissues and returns deoxygenated blood back to the heart.

The liver synthesizes major plasma proteins like albumin and fibrinogen.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Circulatory System - Comparative and Evolutionary Aspects
Cardiac muscle requires a continuous oxygen supply for contraction.

The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs for oxygenation.
