Transportation in plants

        Transportation in plants

1 In Plants transportation is done by xylem and phloem.
2 Collectively they are called conducting tissue.

Conduction of water

1 Root hairs firstly absorb water from the soil by simple diffusion.
2 Root transport water to the element of the xylem.

Element of Xylem

Tracheids         (conduction of water)      
Vessel

Parenchyma    (Food Storage)
Fibres                (Protection)

Transpirational Pull Theory

1 During water conduction.
   Stomata lose excess water from stomata by 
the process of transpiration.
2 Due to transpiration a Section is created in the Xylem, that pulls the water and transports it to the leaves.

The human circulatory system is made up of the heart, blood and blood

Heart

1 Human heart is switched Central of the chest cavity.
2 The heart is tilted towards the left to provide space for the liver.
3 Human Heart is a fist-size organ.
4 It contains four chambers Right Atrium, Left Atrium, Right ventricles and left ventricles.

Blood Vessels

Vessels are tube-like structure that circulates blood throughout the body.

There are two types of blood vessels

1 Artery- Arteries carry oxygenated blood but the Pulmonary artery carries deoxygenated blood. (A.P)
2 Vein- veins carry deoxygenated blood(impure)but pulmonary veins carry oxygenated blood. (Pure)

Capillaries

These are minute vessels that carry blood to the internal parts of the internal organs.

Blood

1 It is fluid connective tissue.
2 Normal person has 5 - 5.5 l of blood in their body.

3 Blood is red due to haemoglobin. (11-16)  

Components of Blood

 Plasma                                     Formed Elements 
     +
 Water                                 a) Erythrocytes(R.B.C)
     +                     
Protein                                b) Leucocytes(W.B.C)
a) Fibrin
b) Globulin                         c) Thrombocytes
c) Albumin                             (Platelets Blood clot)
•Gases Exchange 
 Oxygen, carbon dioxide 
• Immunity or prevent 
  Infection

Function of Blood

1) Blood connective tissue.
2) Provide oxygen to the cells.
3) Transport hormones and nutrients.
4) Blood clotting at the site of injury.

Difference between arteries and veins

     Arteries 
1) Arteries carry oxygenated Blood.
2) Pulmonary artery carries deoxygenated blood.
3) located deep within the body.

Veins
1) veins carry deoxygenated blood.
2) Pulmonary carries oxygenated blood.
3) Peripherally located closed to the skin.

           Double circulation system

1) The blood from tissue is taken by vena cava to sight article.
2) From the sight auricle the blood is supplied left auricle.
3) Pulmonary artery carries blood from the right ventricles to the lungs.
4) In the lungs, The blood is oxygenated and the pulmonary vein supplies this blood to the right articles.
5) From the right auricle blood is supplied to the left ventricles.
6) Aorta carries Oxygenated blood back to the tissue.
7) This flow of blood is called the double circulation system.

Importance of Double Circulation system

1) It maintains blood pressure.
2) It helps to separate oxygenated blood from deoxygenated blood.

     Blood Pressure

The pressure at which blood flows from Hearts to different organs is called blood Pressure. (B.P)
Normal = 120/80 mm Hg 
120= Systole
80=   Dystole

Structure of nephron

                 Structure of nephron 1) Glorerucless 2) Bow Man's capsule 3) Proximal Convoculated tubeless (PCT) 4) Loop of Henle a) Ascending b) Descending 5) Distil C.T 6) Collective tube The function of nephron/urine concentration 1) Ultrafiltration 2) Selective Reabsorption 3) Secretion 1) Ultrafiltration The glomerulus filters the deoxygenated blood into oxygenated blood and transports it back out of the kidney. 2) Selective Reabsorption The different parts of the nephron absorb different materials. P.C.T.- 80% water, glucose, salt Ascending loop of Henle- Urine Vasorecta- Glucose, amino acids D.C.T- Facilitated absorption of 20%water with the help of hormones. 3) Secretion Excess waste is secreted out of getting the kidney. 4)Micturition  The process of throwing urine out of the body through the Urethra is called micturition. This action is Controlled by Lorain. Urine • The human urine is yellow due to Bilruvin secreted by the li...
