Final answer:
The two points that define the latus rectum of a conic section are the endpoints of the line segment that passes through the focus of the conic (like a parabola) and are perpendicular to the principal axis, lying on the conic itself.
Step-by-step explanation:
The student seems to have a question related to conics in mathematics, specifically the latus rectum of a conic section. However, you have provided information related to the human digestive system which is not relevant to the student's query. The latus rectum of a conic section (such as a parabola, ellipse, or hyperbola) is a line segment perpendicular to the principal axis (or the major axis for an ellipse). For a parabola, the latus rectum passes through the focus and its endpoints lie on the parabola itself; these endpoints are the two points that define the latus rectum. The length of the latus rectum is a measure related to the conic's parameters; for instance, for a parabola represented by y^2 = 4ax, the length of the latus rectum is 4a, where a is the distance from the vertex to the focus.
