Human Circulatory System
The human circulatory system is responsible for delivering oxygen, nutrients, and hormones to cells and tissues throughout the body. It consists of the heart, blood vessels and blood. The heart pumps oxygenated blood to the body through arteries and the deoxygenated blood returns to the heart through veins. The circulatory system also helps remove waste products from cells and helps regulate body temperature.

Ascent of Sap
The Ascent of Sap is the movement of water through the Xylem vessels from the roots to the leaves. It is essential for various processes such as photosynthesis, transpiration and respiration. The cohesion-tension theory is widely accepted to explain the mechanism of the Ascent of Sap, where water moves up through the Xylem vessels due to a combination of transpiration and cohesive forces. Factors such as temperature, humidity, and wind affects Ascent of Sap

Blood Coagulation (Blood Clotting)
Blood coagulation or blood clotting is a complex process that prevents excessive bleeding after an injury. It involves platelets, clotting factors, fibrin, and endothelial cells and occurs in a series of steps including vasoconstriction, platelet activation, the coagulation cascade, clot retraction and fibrinolysis. There are many clotting factors involved in coagulation. Disruptions to any of them can lead to bleeding disorders or unwanted blood clots.

Components of Xylem
Xylem is a vital plant tissue responsible for the transport of water and nutrients from the roots to the leaves. It is made up of several components, including tracheids, vessel elements, fibers and parenchyma cells. Tracheids and vessel elements form long tubes that allow for efficient water transport, while fibers provide structural support. Parenchyma cells help with storage and metabolic functions.

15 Difference between Xylem and Phloem
Xylem and phloem are vital plant tissues with different tasks. Xylem transports water and nutrients upwards from the roots, while the phloem transports sugars from the leaves to other parts of the plant. Their composition, flow direction, location, transport mechanism, speed of movement, response to injury, fibres, distribution, movements and roles within plants provide fascinating insights.

Phloem – Definition, Structure, Function, Types and How does Phloem tissue work
Phloem tissue is a type of vascular tissue in plants that transports sugars, amino acids, hormones and other organic compounds from the leaves to the rest of the plant. The tissue is made up of several different types of cells like sieve tube elements, companion cells, phloem parenchyma and phloem fibers. Phloem tissue plays a critical role in plant growth and development by facilitating the transport of hormones, defending against pathogens, transmitting signals and storing nutrients. There are two types of phloem tissue- primary phloem and secondary phloem.
