Give reasons:
Auricles are thin walled chambers.

Assertion Arteries pump blood away from the heart at very low pressure. Reason Arteries have thin wall with large lumen.

passage cells are thin- walled cells found in

Passage cells are thin walled cells found in

Hypnospores are thin walled / thich walled resting spores .

Give the significance of presence of turbinates in the nasal chambers.

Which of the following tissues is made up of thin walled cells?

Assertion:The space between the cornea and the lens is called the vitreous chamber. Reason:The space between the lens and retina is called the aqueous chamber.

Oxygen-rich blood from the lungs comes to the thin-walled upper chamber of the heart on the left. The left upper chamber (A) then relaxes. It then contracts and the blood is allowed to enter the next chamber (B), as it expands. When the muscular left lower chamber of heart contracts the blood is pumped out to the body via aorta. Deoxygenated blood reaches from the body to the upper chamber on the right side of heart (C) and it expands. As this part contracts, the corresponding lower chamber (D) dilates. This transfers the blood to right ventricle, which in turn pumps it to the lungs for oxygenated. Which chambers of human heart contain oxygenated blood?
