PLANT TRANSPORT AND ANIMAL CIRUCLATION

Plant Transport

Involves absorption of water through roots and movement of substances in phloem.

Xylem

Transports water and dissolved substances from roots to aerial parts of the plant.

Phloem

Transports food molecules bidirectionally within the plant.

Photosynthesis

Process where plants make their own food using carbon dioxide, minerals, and water.

Animal Circulation

Blood flow through the human heart involves oxygenated blood entering the left side of the heart from the lungs.

Kidney Function

Kidneys play a crucial role in maintaining fluid balance and eliminating metabolic wastes.

Antidiuretic Hormone (ADH)

Promotes water conservation, secreted from hypothalamus via pituitary.

Aldosterone

Enhances sodium reabsorption, stimulated by drop in blood pressure.

Hypothalamus Thirst Center

Inhibits saliva production and stimulates drinking urge

Receptors in Juxtaglomerular Apparatus

Function in kidney's autoregulation system
