Heart Dissection

Did you know that a human heart is roughly the size of your fist and beats over 100,000 times a day? Today, students had an amazing opportunity to hold and study a real heart! After reviewing a heart’s function and how blood flows through the heart, students received sheep hearts. They first had to figure out which side was the front and which side was the back, a task easier said than done! They then studied the vessels that branch off of the heart by sticking their fingers in them to follow their paths. They then opened up the hearts to investigate the chambers on the inside of this important organ. Ask your student why the chordae tendinae (or heartstrings) are so important!

Students did a great job managing their dissections and identifying key features!

 

Disección de Corazón

¿Sabías que el corazón humano es aproximadamente del tamaño de un puño? ¿y que late más de 100.000 veces al día? Hoy, los estudiantes tuvieron la gran oportunidad de aprender sobre el corazón y, ¡de tener uno en sus manos! Después de repasar las funciones del corazón y cómo la sangre fluye a través de éste, los estudiantes trabajaron con corazones de ovejas. Primero tuvieron que descifrar qué lado del corazón corresponda a la parte frontal y cual a la posterior; tarea que es más fácil decir qué hacer. Después, estudiaron los vasos sanguíneos que se ramifican fuera del corazón, para lo cual introdujeron sus dedos en los vasos y siguieron su “camino”. Luego, abrieron los corazones para investigar las cámaras que componente a este órgano tan importante.  Pregúntele a su hijo o hija por qué las chordae tendinae (en latín) o cordones (también cuerdas) tendinosos son tan importantes.

Los estudiantes hicieron un gran trabajo en sus disecciones e identificando partes claves del corazón.
