Eye diagram |
| Answer» Eye:\xa0Eye is a hollow spherical structure composed of three coats:– Outer fibrous coat– Middle vascular coat– Inner nervous coat(i) Fibrous coat: It is thick and protects the eyeball. It has two distinct regions – sclera and cornea. Sclera covers most of the eye ball. The sclera or white of the eye contains many collagen fibres. Cornea is a transparent portion that forms the anterior one – sixth of the eyeball. The cornea is avascular (i.e., lacks blood supply).(ii)Vascular coat: It comprises of 3 regions : choroid, iris, ciliary body.(a) Choroid : It lies adjacent to sclera and contains numerous blood vessels and pigmented cells.(b) Iris: The iris is a circular muscular diaphragm containing the pigment giving eye its colour. It extends from the ciliary\xa0body across the eyeball in front of the lens. It 2. has an opening in the centre called the pupil.It contains two types of smooth muscles, circular muscles (sphincters) and radial muscles (dilators), of ectodermal origin.(c) Ciliary body: Behind the peripheral margin of the iris, the vascular coat is thickened to form the ciliary body. It is composed of the ciliary muscles and the ciliary processes.(iii) Nervous coat: It consists of retina which is neural and sensory layer of an eye ball.\xa0It consists of three layers; ganglion cells, bipolar cells and photoreceptor cells (rods and cones).Lens: It is a transparent, biconvex, elastic structure that bends light waves as they pass through its surface. It is composed of epithelial cells that have large amounts of clear cytoplasm in the form of fibres.Chambers of eyeball: The lens, suspensory ligament and ciliary body divide the eye into an anterior aqueous chamber and a posterior vitreous chamber which are filled with aqueous humour and vitreous humour respectively. | |

Write a shote note on prions |
|
Answer» Srry.... biological classification Biology classification Ye kon se chapter ka h?? A prions is an infectious agent\xa0composed of protein\xa0in a misfolded form. Prions propagate by transmitting a misfolded protein amyloid\xa0fold, in which the protein polymerises into an aggregate consisting of tightly packed state. When a prion enters a healthy organism, it induces existing, properly folded proteins to convert into the disease-associated, prion form; the prion acts as a template to guide the misfolding of more proteins into prion form. These newly formed prions can then go on to convert more proteins themselves; this triggers a chain reaction that produces large amounts of the prion form. All known prions induce the formation of an beta sheets. Amyloid aggregates are fibrils, growing at their ends, and replicating when breakage causes two growing ends to become four growing ends.

Counter current mechanism |
|
Answer» The counter current mechanism operating inside the kidney is the main adaptation for the conservation of water. There are two counter current mechanisms inside the kidneys. They are Henle’s loop and vasa rectae.Henle’s loop is a U-shaped part of the nephron. Blood flows in the two limbs of the tube in opposite directions and this gives rise to counter currents. The Vasa recta is an efferent arteriole, which forms a capillary network around the tubules inside the renal medulla. It runs parallel to |

Diagram for double circulation |
| Answer» The human\xa0circulatory\xa0system is a\xa0double circulatory\xa0system. It has two separate circuits and blood passes through the heart twice: the pulmonary circuit is between the heart and lungs. the systemic circuit is between the heart and the other organs. Blood gets pumped out of the heart. This blood goes to different organs and then blood again comes back to the heart. All this happens in a very systematic way through the different arteries and veins carrying oxygenated and deoxygenated blood. In\xa0double circulation, there are two pathways in which blood flows. | |

What Function of nephron |
| Answer» Functioning of nephron:Filtration of blood takes in Bowman’s capsule from the capillaries of glomerulus. The filterate passes into the tubular part of the nephron. This filterate contains glucose, amino acids, urea, uric acid, salts and a major amount of water.\xa0Reabsorption: As the filterate flows along the tubule useful substances such as glucose, amino acids, salts and water are selectively reabsorbed into the blood by capillaries surrounding the nephron tubule.\xa0The amount of water reabsorbed depends on the need of the body and also on the amount of wastes to be excreted.\xa0The filterate which remained after reabsorption is called urine. Urine contain dissolved nitrogenous waste i.e., urea and uric acid, excess salts and water. Urine is collected from nephrons by the collecting dust to carry it to the ureter. | |
