For survival and to execute diverse activities, all living beings require food, water, and oxygen.
In the digestive system, food is broken down into simple absorbable components known as nutrients.
The circulatory system aids in the transportation of nutrients such as glucose, amino acids, and lipids throughout the body.
Every cell receives absorbed nutrients via the blood, a circulating fluid tissue.
The excretory system is in charge of removing waste from various regions of the body.
Every cell produces waste into the bloodstream, which is then delivered to the excretory organs for removal.
Animals’ Transportation
Food, water, and oxygen are essential for creatures to survive.
The circulatory system is responsible for supplying these essential necessities to each bodily part of animals in order for them to obtain energy.
Furthermore, waste formed within the animal’s body should be transported to the excretory system.
System of Circulation
Blood, blood arteries, and the heart make up the circulatory system.
It entails the blood transporting oxygen, minerals, and nutrition to all bodily parts.
Blood is a blood fluid that is red due to the presence of haemoglobin in it.
Haemoglobin is the protein that transports oxygen throughout the body.
There are three types of cells in blood.
RBCs deliver oxygen from the lungs to various regions of the body, as well as carbon dioxide from various areas of the body to the lungs.
Immunity to invading microbes that can cause sickness and infection is provided by white blood cells (WBC).
Platelets: Platelets form a shield-like structure at the site of injury to stop bleeding; this is referred to as blood clotting.
Plasma is the fluid element of the blood that contains both cells and fluid.
Blood vessels are the pipe-like structures that allow blood to flow through them.
Blood Vessels are divided into three categories:
Arteries transport oxygenated blood from the heart to the tissues of the body.
Veins transport deoxygenated blood from the tissues of the body to the heart.
Capillaries: Capillaries operate as a binding agent, tying arteries and veins together.
The heart is a muscular organ that is located on the left side of the chest and is the size of a fist.
Because it aids in the delivery of oxygen and other nutrients through the blood, it is the most vital organ in our body.
The heart is separated into four chambers to prevent the mixing of oxygenated and deoxygenated blood.
The left and right atriums are the upper two chambers of the heart, and they are known as atria.
The left ventricle and right ventricle are the lower two chambers of the heart, and they are known as ventricles.
The contraction and relaxation of the muscles that make up the walls of the heart chambers is known as heartbeat.
Animals’ Excretion
Excretion is the process of removing undesired or waste material from the body.
Exhalation is the process through which carbon dioxide is expelled from an animal’s body.
Egestion is the process by which undigested food is expelled from the animal body.
Human Excretory System
The excretory system is responsible for the elimination of waste materials from the body.
The kidney, ureter, urinary tract, and urethra are all part of it.
Kidney: The kidney is a bean-shaped organ whose main function is to filter blood and excrete waste in the form of urine.
Urinary Bladder: This organ stores pee so that urination does not have to be constant.
The ureter is a pipe-like structure that connects the kidney and the urinary bladder, allowing urine to move from the kidney to the bladder.
The urethra is a urinary hole that permits urine to exit our bodies.
Plants’ Transportation
Plants use their vascular system to transport water, nutrients, food, and waste from one region of the plant to another, allowing them to fulfil a variety of activities. Xylem and Phloem are the two types of tubes that make up the xylem.
A tissue is a collection of cells that serve a specific purpose in an organism. Xylem is the vascular tissue that transports water and nutrients in plants, while phloem transports the organic products of photosynthesis.
Vascular bundles are a compact structure made up of both xylem and phloem.
Xylem
The xylem forms a network of channels that serves to transport water and dissolved minerals from the roots to the leaves via the stem. They’re mostly made up of decomposing cells.
Phloem
Food is translocated downward, from the leaves to all sections of the plant, through vessels called sieve tubes in phloem. They are made up primarily of living cells.
Transportation Minerals and Water
Plant roots include small outgrowths called root hairs that allow water and dissolved mineral salts to pass through.
The root hair expands the surface area available for water and mineral salt absorption. Osmosis is a method by which roots absorb water from the soil.
Osmosis is the movement of water across a cell membrane over short distances from a higher concentration to a lower concentration.
Water and mineral salts are continuously absorbed by the root cells from the soil.
By transpiration, some of the surplus water collected by roots is released as water vapour through stomata in the leaves.
This causes a suction pull, causing water to rise to tremendous heights in tall trees. The plant is also cooled through transpiration.
