In this Video, Dr. Priyanka Dadupanthi, Assistant Professor, Biyani Group of colleges, describes about physiology of circulating system. Heart is important part of circulating system. Heart beat generates through systole and diastole. Rhythmic contraction & relaxation in heart is known as Heart beat or cardiac cycle. Cardiac cycle divided into three stages: Arterial systole, ventricular systole and ventricular Diastole.

In this Video, Dr. Umesh Garu, Assistant Professor, Biyani Group of colleges, describes about specification which is environmental process includes the origin of one or more species from an ancestral species. It depends on the environmental condition and population.

In this video Dr. Priyanka Dadupanthi, Biyani Groups of Colleges, Jaipur, Rajasthan (2014) , explains about the structure of compound eye of Prawn. Compound eyes are the typical feature of arthopods (crustaceans and insects). These are dark coloured. www.gurukpo.com, www.biyanicolleges.org

In this video,Dr. Priyanka Dadupanthi, Asst. Professor, Biyani Girls College is explaining about the Malpighian tubule which is the excretory organ of insects. These are yellow in colour. Number of these tbules are approximately150. These are present at junction of mesenteron and ileum.Tubule has two parts- 1. Distal (Secretory) 2. Proximal (Absorptive) Uric acid which is already present in haemolymph combines with potasium bicarbonate and water molecule and formed potasium urate. This again combines with salts and formed potasium bicarbonate and uric acid. This uric excrete in solid form.

In this video Dr. Priyanka Dadupanthi, Asst. Professor, Biyani Girls College is explaining about the Flame cells or protonephridia which are the important part of protonephridial system. This system is concerened with excretion and osmoregulation in Platyhelminths (Fasicola hepatica). These are arising from basal granules. The term “flame” is due to vibrant like flickering of these structures. Excretory products diffuse into flame cells. From mesenchyme of these cells these products are pushed into longitudinal excretory canal and finally pushed outside by excretory pore.

This video is about Excretory System. Parts of this system are Kidney, Ureter, Urinary Bladder and Urethra. Kidney and ureter are paired. Wall of urinary bladder is muscular. Adernal gland is present on the top of both kidneys. In T.S. of kidney we can see cortex and medulla. Cortex is outer and medulla is inner part.

Interval notation is a way of writing subsets of the real number line. A closed interval is one that includes its endpoints: for example, the set {x | –3 x 1} To write this interval in interval notation, we use closed brackets [ ]:example-[-3,1]An open interval is one that does not include its endpoints, for example, {x | –3 x 1}. To write this interval in interval notation, use Open brackets()

This mechanism is divided into four steps.
1. Excition
2. Excitation contraction coupling
3. Contraction
4. Dilation

This video is about Blood Groups. Landsteiner and Veiner describe two systems to identify blood groups. One of them is ABO system and other is Rh system. These systems are based on antigen and antibody activity. According to ABO system four blood groups are present like A, B, AB and O. AB blood group is universal receptor while O is universal donor. Rh factor may be present or absent in blood. If present it is known as positive blood group.
